Dow, S&P 500 end down; bond trading revenues bites bank profits

The Dow and S&P 500 slipped with the S&P retreating from the previous session's record high, after earnings from Goldman Sachs and other banks disappointed investors.

Financials were the biggest drag on the market after both Goldman Sachs Group Inc and Citigroup Inc reported that lower bond trading revenue took a bite out of their quarterly profits. Goldman's earnings fell 21 percent.
